In one of our site we are in requirement of a -24 VDC supply. The instrument installed is key phasor which accepts -24 VDC as power and our's is +24 VDC.

Is there any way we can convert +24 VDC to -24 VDC...

    Am I missing something here? If the supply is a floating one, all you need to do is to connect it in reverse. Make positie the ground, then the negative becomes your -24 v.
